The object which I'have inview is the .pro-

- pensive-construction,

' :In theaccompanying. drawings, kwherein .I lhave illustrated aV practical` embodiment of l the principles Lofv Ury-.invention7 .Fig. .1..is a

.10 longitudinal. and `vertical, .section` of.- the furnace.

rFig. 12 is .a horizontalsection. taken ...along theiline 2-.2, inFig.;1.

Figs 3, #tand ,5, are vertical sectionsl taken along the lines 13.-.3', 4.-,41and 5 5 in Fig. 1, respectively.

Referring tothe .drawings,. the furnace is provided ywith ,a bottom floor 1; front side wall 2; rear side Wall; frontend wall 4 and rearend wall 5. .6 represents the transversely arched roof, adj acentvr to the rear, end wall l5 y is a cross-partition wall 7y which isV provided with the port 8 throughwvhich the lgaseous products escape from the main furnacecham- .ber9`of the combustion chambersl() comprising thespace between the partitionj7 `and the rear end wall 5.

Theport 8 is in the upper 4portion of the partition wall 7 l,and they Alower portionof kthe chamber 10 is provided Withanarched opening 11 which leads into the lower end .of A.the

The chimney. 12 is provided with a damper 13 for regulating the draft.I

The frontV side wall 2 is provided witha clean-out port Y14 leadingV into the bottom of the chamber 10 for the withdrawalof ashes and other precipitates from the chamber.

15 represents the yfire box which is erected inthe vmain furnace chamber and is adjacent to the front end of the latter.

'The fire box is preferably near to, but not at the front end of the furnace. The re box extends for the fu'llwidthof the furnace and its frontandrear walls `are formedby the side walls of the furnace.

.an ash door 19.

the fire box, extending transversely of the furrnace. Above said grate bars the wall 2 of the .furnace is. provided with a doored opening -18 for theintroduction ofthe fuel While below the grate bars said wall is provided with .20 represents transversely. disposed arches spanning` the .main vfurnace chamber from side wall to side wall and spacedy apart substantially .asishown in Fig. y1. The arches are preferably made of refractory brick or tile.

`VVherethe fire box is spacedv from the yfront end wall of the furnace such arches are providedatboth sides of the J'ire box as shown. y

' The arches areon the same horizontal level vas the roof `of theire box and preferably have l the same arc of curvature.

A longitudinal base wall 21 extends upwardly from the floor of the furnace beneath the arches-20, said wall being preferably slightlygnearer. the rear side Wall 3 than the f'front side wall 2.

'22 represents. a fiat hearth or deck of refractory material supported at its rear by the Awall Sand at its front by the top of the basel Wall 21.

v 23 represents grate bars extending from the :front of the base wall 21 to the side wall 2 beneath the arches 20.

The front wall 2 is provided with clean-cut openings24 above the grate-bars 28 and ashremovalopenings 25 beneath said bars.

able ports oropenings for the passage of the v products of fuel-combustion to the space or spaces lunder thelarches 20. Thus said walls may be of checker ,Work as shown at 27. The

.roofof the furnace is provided with suitable openings 28 above the arches 20 through whichf-thegarbage and the refuse is dumped onto the arches 20. The openings 28 are provided with removable lids or closures 29.

Above the arched roof 6 the furnace is provided with a fiat top .80 leaving an air space or chamberl 3l between the top and roof, the

openings 28 being` walled through said chamber, as shown in Fig. l.

The side walls 2 and 3 are provided with Yports 32 leading into said chamber 3l from outside atmosphere, and a port 33 connects ysaid chamber 31 with theV chimney 12, thus providing forcurrents of airpassing through thechamber. 31 for preserving thearched roof 6. Y

The garbage andother refuse is dumped through the opening 28 falling down upon the` arches 20 where 'it is subjected from below tothe products of the fuel-combustionin the lire box. l i

As it becomes dried and partially consumed it falls down between the arches 20, the dumped material falling upon or Vbeing pushed onto the hearth 22 for further dryf ing. f y The drier material is supported on the grate bars 23 until consumed.V As the ma" terial on the hearth .22 becomes dried, is

raked vforward on thegrate bars 23. VPokers or rakes may be'inserted through the stoke openings 26 to distribute the mass of material on the arches 20 and, if necessary,

consumed, the chimney carrying olf the residuant gaseous water which isn-ot offensive.

What I desire to claim is l. In a furnacek of the character described, the combination with a main furnace chamber, a combustion chamber and a chimney connected vto the latter, oftransversely disber upon whichl the material to be consumed posed and spaced supports in said main'chamisplaced, the communication between said chambers being above said supports, and a Vroofed overiire boxV located in said main Y box.y

chamber ybetween the ends thereof and Vhaving communication with the latter below said supports, said lire box roof having its upper surface level with the tops of said supports Vto permit material to be moved from one end Y of the main chamber to the other over the fire 2. In a furnace of the character described, the combination with a main furnacechamber, a combustion vchamber land a chimney7 connected to the'flatter, of a fire box located'A in the lower portion of the main chamber between the ends thereof and having a closed top and ported side walls, and transversely disposed and spaced supports in said main chamber inl front of andbehind they fire box 'the latter,the material ybeing pla'cedontheV supportsand the 'side walls of the `fire .box .'85, l
